Cathy gave me these two puzzles for my birthday. I do enjoy puzzles and these were quite nice. The first that I tried, on the right, was labeled as Kepler’s Planetary Puzzle. Apparently it is more properly known as a Chuck puzzle, invented in 1897 by Edward Nelson. It is a form of Burr puzzle, a three-dimensional puzzle of interlocking pieces, often made of wood. This was a bit tricky but I managed to get it back together in about a half hour. The second, on the left, was labeled as Hubble’s Galaxy Puzzle and that took me a little longer. It took nearly an hour, with the first 45 minutes or so being trial and error (mostly error). Once I figured it out, it took another 15 minutes or so to actually get all the pieces together.
